| 内容記述 | The sodium line reversal method of determining the temperature of a flame was applied to the engine flame. A special cylinder, with two quartz windows, that would cause a beam of light from the source to pass through the combusion chamber, was constructed. Upon adding a small quantity of sodium ethylate to the fuel, the temperature of the engine was compared with the apparent temperature of the light source. A tungsten pointolite, a tungsten lamp, and a carbon arc lamp were used as the light source. The D-line intensity of the flame was measured by a photoelectric cell. Comparison of this intensity with its flame temperature showed that there is thermal equilibrium between the sodium vapour and the engine flame. The temperature measured by this method is the correct temperature of the flame. The spectrum in the visible region of the engine flame consisted of CH 4300 A°, CC Swan bands, and the continuous bands. The spectra obtained at various crank angle showed that as the crank angle proceeds, the CH and CC bands become fainter, and that the temperature in the cylinder is not uniform. The maximum temperature at various air fuel ratios was measured with the engine running at 800 r.p.m.. Although the correct air fuel ratio in the fuel under test was 13.8, the temperature was always maximum at 11.5, which is higher that obtained by Hersley and Panton and nearly agrees with the calculated value. | |||||||||
